Hey all, looking for some input on a couple items. I attached a quick rough diagram to help show a portion of my setup I'm working on and where my fusing questions are.
I'll have a Lynx Shunt with a Distributor on each end, the battery side and the load side. the fuse for the Lynx Shunt takes a CNN fuse and Victron calls this the System fuse. makes sense because all the loads go through this location.
Victron recommends a 400A fuse on the multiplus II for the DC connection so that's what I'll use there. The BatteryProtect is a 220A model so I'll go with a 250A fuse there. I have the 150/100 MPPT so I chose a 125A fuse there. Thats the gist of it for my load side..
On the BatteryProtect, I don't expect to be running 220A continuous. This is on my RV which is mostly LED lights and smaller items, the only larger DC loads are my leveling system (which wouldn't be used while everything else is running) and my Generator start which is only a momentary load up to 95amps while it's starting.
I'm looking for some input on fuse size for the Lynx Shunt "system fuse" as well as my individual battery fuses. I'm thinking whatever my Lynx Shunt fuse is, should my batteries each be half of that? They are the 280aH EVE cells. each battery will be a 12v 560aH battery config, and I'll have two of those in parallel but they'll each have their own fuse.
